The bill establishes a child tax credit for resident individual taxpayers in Kansas, effective for tax year 2025 and subsequent years. The credit amount varies based on the taxpayer's adjusted gross income, with a maximum credit of $600 for those earning up to $25,000, decreasing incrementally to $25 for those earning over $350,000. Married individuals filing separately can claim half the credit amount they would have received if filing jointly. Additionally, the bill mandates that all income thresholds and credit amounts will be adjusted annually based on the cost-of-living adjustments as determined by federal law.

The legislation also includes provisions for the refund of any excess credit amount that exceeds the taxpayer's income tax liability. It requires the Secretary of Revenue to compile and submit an annual report detailing the child tax credit's impact, including the number of recipients and the total amount of credits issued. The definition of a "qualifying child" is specified, including criteria such as age, residency with the taxpayer, and support provided. Overall, this bill aims to provide financial relief to families with children through a structured tax credit system.
